Celtics coach Doc Rivers, appearing on the Dennis & Callahan Show, said that shooting guard Ray Allen was hampered by a hamstring injury during the series against the Orlando Magic. "Ray had a hamstring problem throughout the Orlando series," said Rivers. "In Ray’s case, I thought his hamstring was bothering him a lot. That could have had an effect on him."

Rivers also said that, in addition to the surgery that Kevin Garnett will require on his right knee, Kendrick Perkins likely will require a procedure on his injured shoulder, and that Paul Pierce "had some bone spurs that may need to be removed as well."

Rivers also said that the Celtics required some additions for the 2009-10 season.

"We have to improve our team. There’s no doubt about that. We don’t have to make any changes, but we do need some additions," said Rivers. "We need a small forward who can defend, who can make shots and give (Pierce) a blow."

For more, including Rivers talking about how much longer he plans on coaching, what kind of offseason additions the Celtics will look to make, and whether the coach thinks that Glen "Big Baby" Davis or Stephon Marbury will be back, either listen to the audio (click here[1]) or read the transcript at the Green Street Blog[2].
